The Broadbalk long-term experiment at Rothamsted : what has it told us about weeds?
Moss, S.; Storkey, J.; Cussans, John W.; Perryman, S.A.M.; Hewitt, M.V. (2004)The Broadbalk experiment was started in 1843 to investigate the relative importance of different plant nutrients (N, P, K, Na, Mg) on grain yield of winter wheat. Weeds were controlled initially by hand hoeing and fallowing, ... -
The combination of a simulation and an empirical model of crop/weed competition to estimate yield loss from Alopecurus myosuroides in winter wheat
Storkey, J.; Cussans, John W.; Lutman, P.J.W.; Blair, A.M. (2003-12)An empirical model of yield loss from assessments of relative weed green area (weed green area/weed + crop green area) was fitted to data from a series of competition trials of winter wheat and black-grass (Alopecurus ... -
A functional group approach to the management of UK arable weeds to support biological diversity
Storkey, J. (2006-12)Weeds have an important role in maintaining farmland biodiversity. This needs to be balanced with their potential negative impact on crop yield and quality. Mechanistic models of crop-weed competition are an important tool ... -
Modelling assimilation rates of 14 temperate arable weed species as a function of the environment and leaf traits
Storkey, J. (2005-09)Information on the response of assimilation rate to environmental factors is lacking for many less competitive weed species that need to be considered in the context of increasing farm biodiversity. A pot experiment was ... -
Modelling seedling growth rates of 18 temperate arable weed species as a function of the environment and plant traits
Storkey, J. (2004-06)Background and Aims: The early growth rate of seedlings in the exponential phase is an important ecophysiological trait in crop/weed competition models based on assessments of relative weed green area. An understanding of ... -
Providing the evidence base for environmental risk assessments of novel farm management practices
Storkey, J.; Bohan, D. A.; Haughton, A. J.; Champion, G. T.; Perry, J. N.; Poppy, G. M.; Woiwod, I. P. (2008-11)An environmental risk assessment of a new agricultural management practice depends upon the provision of empirical evidence of cause and effect. This will invariably be derived from comparative experiments testing the null ... -
Relationship between temperature and the early growth of Triticum aestivum and three weed species
Storkey, J.; Cussans, John W. (2000)Experiments were conducted in controlled environments and in the field on winter-hardy Triticum aestivum and three weed species commonly found in cereal fields in the United Kingdom to examine whether overwinter shoot ... -
Using Assembly Theory to Explain Changes in a Weed Flora in Response to Agricultural Intensification
Storkey, J.; Moss, Stephen R.; Cussans, John W. (2010)The intensification of crop management in the U.K. over the past 60 years has resulted in the decline of the Populations of a number of annual plant species adapted to arable habitats. In contrast, other species continue ...
